We're dividing 975514 by 78 
The aim is to understand the frequency of 78 in 975514.

Let's proceed to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 78

Moving on to step 2:
78 can be fit into 97 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 19 after subtracting 78 from 97.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 78

Moving on to step 3:
If we divide 195 by 78, we get 2 and a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 156 from 195, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 78

Advancing to step 4:
If we divide 395 by 78, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 390 from 395 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 78

Going ahead to step 5:
When dividing 51 by 78, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 1250.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 78

Step 6:
78 can be fit into 514 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 12506.0
Subtracting 468 from 514 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 12506.5
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 12506.58
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
If we divide 760 by 78, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 12506.589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
When dividing 580 by 78, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 12506.5897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 12506.58974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 12506.589743
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 12506.5897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
78 goes into 700 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 12506.58974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 12506.58974358, with a leftover of 7.6e-08.
